Poly variable signal deisutoriibiyuta

摘要

PROBLEM TO BE SOLVED: To provide a multivariable signal distributor which is suitable for a multivariable process measurement control system needing advanced control and accomplishes measurement distribution and the opening of measurement control.;SOLUTION: When a plurality of quantities of state of a control object 1 are entirely measured with an independent configuration by each single quantity of state by using a measurement signal 2 of an international standard 4 to 20 mA DC current, converted into a 1 to 5 V DC voltage 51 and transferred to a controller 4, this multivariable signal distributor 5 assigns a means 52 capable of identifying the quantities of state (main controlled variable/secondary controlled variable/distinction of disturbance quantity) and also makes the signal to a distribution signal 3 having versatility by attaching its target value 53 to the main controlled variable and its reference value 54 to the disturbance quantity by using 1 to 5 V DC voltage signal.;COPYRIGHT: (C)2001,JPO
